Demand for slimline heritage units sees Slenderline Glass skyrocket

Slenderline Glass, the renowned manufacturers behind the Slenderline range of advanced slimline heritage units, are pleased to report the firm has grown by a remarkable 40% in just the last 12 months.

The Kent-based firm which is part of the E.J. Cocker Group has seen incredible demand for their heritage sealed units thanks to significant investment and a nationwide brand-building strategy undertaken with marketing partners Purplex.

“We are absolutely delighted to report this fantastic achievement for Slenderline Glass,” comments Andy Cocker, Director at Slenderline Glass. “The last 12 months have been incredibly busy as demand has skyrocketed and more joiners, builders and installers across the country discover Slenderline’s unique proposition. We are incredibly proud especially as the market becomes even tougher for smaller sealed unit manufacturers like us.”

According to the latest industry report conducted by Insight Data, the number of IGU manufacturers is decreasing as large-scale manufacturers dominate the market, producing thousands of sealed units every week. However, the specialist nature of Slenderline’s heritage sealed units mean they have not only been able to buck the trend but become one of the industry’s fastest growing manufacturers.

“Our sealed units prove so popular because they offer authentic, heritage aesthetics with cutting-edge thermal performance thanks to specialist warm edge technology. We believe this provides joiners, builders, contractors and installers with an opportunity to really stand out from their competitors and confidently enter the heritage market with a unique and proven conservation-friendly product.”

Launched as a stand-alone business in 2012 after impressive demand for E.J. Cocker’s heritage operation, Slenderline Glass has consistently grown year-on-year. Last year was a monumental year for the firm, doubling the size of its state-of-the-art manufacturing facility in Kent and investing in additional machinery to not just keep up with incredible demand but uphold Slenderline’s high standards of quality and authenticity.

Andy concludes: “The secret to our growing success is not standing still, we have continued to invest heavily in everything from our facilities to our marketing through Purplex. The strength of our product range and the increased nationwide exposure have combined to help push Slenderline Glass to the forefront of the heritage market. 2018 has been fantastic so far and all the signs are pointing towards another exciting, successful, 12 months for Slenderline Glass.”
